try to use the sssd package and encounter two problems.
firstly, it seems that it is not adapted for void runit service.
there is a /etc/rc.d/init.d/sssd file but nothing in the /etc/sv/ directory to start the service
secondly, a dependency problem. this package needs libtevent (error when installing)
but did not proposed to install the tevent package.
don't know if it is the right place for this feedback. it is my first post.
